Use of fly ash for remote filling of underground cavities and passageways
Methods are described for filling underground cavities remotely with dry material pneumatically injected through borehole to seal openings, prevent air movement, and reduce subsidence; this often brings underground fires under control by limiting access of air; based on results of large-scale tests conducted by U S Bureau of Mines it has been ascertained that fly ash, because of its low angle of repose and good flow characteristics, was most suitable stowing material.
